Description

Technical Field

[0001] The invention belongs to the technical field of rice husker, and more specifically, relates to a rubber roller gap compensation device for a rice husker. Background Art

[0002] Existing rice hullers often use two rubber rollers rotating in opposite directions to achieve the hulling of grains. During the long-term use of the rice huller, the rubber rollers will be worn. The wear of the rubber rollers will reduce the diameter of the rubber rollers and increase the gap between the two rubber rollers, that is, the rolling distance will increase. During the operation of the rice huller, the rolling distance between the two rubber rollers needs to be within a certain range to ensure the hulling effect of the grains. The increase in the rolling distance of the rubber rollers will affect the hulling effect of the grains. Therefore, it is necessary to regularly adjust the wheelbase of the two rubber rollers or replace the rubber rollers regularly. When adjusting the wheelbase of the rubber rollers, the existing rice huller often always applies a certain thrust to one rubber roller, so that the rubber roller always approaches the other rubber roller to ensure that the surfaces of the two rubber rollers can still contact or maintain a constant gap after the diameter of the rubber rollers is reduced due to wear. This adjustment method is often difficult to control the pressure between the rubber rollers on the grains, especially when the grain feed flow rate is large, it is easy to increase the crushing rate of the grains, which is not conducive to the use effect of the rice huller.
